HEDDLE Filed March 2, 1940 Patented July 15, 1941 UNITED STATES PATENTOFFICE HEDDLE Otto Mahler, Monbard, France Application March 2, 1940,Serial No. 321,944 In Switzerland February 26, 1939 6 Claims. (Cl.13993) My invention relates to improvements in weaving heddles as used,in particular, for weaving endless fabrics and which are made of steelflats; and the objects of my improvement are, first, to provide meansfor engaging and disengaging the heddle with and from the warp thread bya single turn of the heddle and without the necessity of bending backand straightening the latter; second, to prevent the cutting in orspring out of the warp thread upon a downward movement of the warp;third, to permit of manufacturing a heddle with an eyelet open on oneside and which also can be locked, from steel flats; and, fourth, togenerally decrease the number of and time required for manual operationsin weaving and to produce a better fabric.

I attain these and related objects by the heddle illustrated in a numberof modifications in the accompanying drawing, in which- Figs. 1, 2 and 3show one modification respectively in front elevation, side elevationand horizontal section through the eyelet; Figs. 4 and 5 show anothermodification respectively in front elevation and in horizontal sectionthrough the eyelet; Fig. 6 is a front elevation of a third modification;Fig. '7, a front elevation of a fourth modification; and Figs. 8 and 9,a fifth modification respectively in front and in side elevation.

I and l are the two legs of the heddle, 2 is the riveted or weldedjuncture of the legs, and 4 is the eyelet.

In the modification shown in Figs. 1-3 the recesses 3 and 3 of the legsform the eyelet 4. The leg I stays in front, and the leg I in the rear,while the eyelet 4 is turned out of the plane of the legs, e. g. to theamount of 45. 7

In the second modification according to Figs. 4 and 5, the legs arecranked at the eyelet, at right angles to their plane. In this case theleg I extends from the top front to the bottom rear, and the leg I fromthe top rear to the bottom front. Here also, the eyelet 4 is turned outof the plane ofthe legs.

In the modification shown in Fig. 6, the eyelet 4 is formed by thelateral bends 6, 6' in the plane of the legs and also turned outthereof. The leg I stays in front, and the leg I stays in the rear.

In the design according to Fig. 7, the legs are cranked at 5, 5' atright angles. The leg! extends from the top front to the bottom rear,and the leg I from the top rear to the bottom front,

while the eyelet 4 is turned out of the plane of the legs.

In the design according to Figs. 8 and 9, the eyelet 4 is formed by thebends 1, I of the legs projecting out of the plane of the latter.

What I claim and desire to secure by Letters Patent is:

1. A heddle particularly adapted for manufacturing endless fabrics,comprising at least two flat legs arranged in juxtaposition to eachother, said legs being deformed intermediate the ends thereof and theresultant deformations defining an eyelet, and a juncture of said legslocated to one side of said eyelet and in close adjacence theretowhereby, in effect, a closure for said eyelet is formed, the remainderof the eyelet being open throughout, whereby the heddle may be readilyengaged with and disengaged from warp thread.

2. A heddle'particularly adapted for manufacturing endless fabrics,comprising at least two flat legs arranged in juxtaposition to eachother, each of said legs being provided on one edge thereof intermediateits ends with a recess, said recesses being formed in opposite edges andbeing of such extent as to overlap each other to define an eyelet, and ajuncture of said legs located to one side of said eyelet and in closeadjacence thereto whereby, in effect, a closure for said eyelet isformed, the remainder of the eyelet being open throughout, whereby theheddle may be readily engaged with and disengaged from warp thread.

3. A heddle particularly adapted for manufacturing endless fabrics,comprising at least two flat legs arranged in juxtaposition to eachother, each of said legs being deformed intermediate the ends thereof toform a laterally offset bend, said bends extending in oppositedirections to such extent as to define an eyelet, and a juncture of saidlegs located to one side of said eyelet and in close adjacence theretowhereby, in effect, a closure for said eyelet is formed, the remainderof the eyelet being open throughout, whereby the heddle may be readilyengaged with and disengaged from warp thread.

4. A heddle particularly adapted for manufacturing endless fabrics,comprising at least two fiat legs arranged in juxtaposition to eachother and extending in side-by-sideparallel relation-1 shipsubstantially along the entire extent thereof, said legs being deformedintermediate the ends thereof and the resultant deformations defining aneyelet, and a juncture of said legs located to oneside of said eyeletand in close adjacence thereto whereby, in effect, a closure for saideyelet is formed, the remainder of the eyelet being open throughout,whereby the heddle may be readily engaged with and disengaged from warpthread.
